This disclosure provides antibodies that specifically bind to and typically neutralize botulinum neurotoxins (e.g., BoNT / A, BoNT / B, BoNT / E, etc.) and the epitopes bound by those antibodies. The antibodies and derivatives thereof and / or other antibodies that specifically bind to the neutralizing epitopes provided herein can be used to neutralize botulinum neurotoxin and are therefore also useful in the treatment of botulism.

The present disclosure provides antibodies that specifically bind to botulinum neurotoxins (e.g., BoNT / A, BoNT / B, BoNT / C, BoNT / D, BoNT / E, BoNT / F, BoNT / G, etc.) and the epitopes bound by those antibodies. The antibodies and derivatives thereof that specifically bind to the neutralizing epitopes provided herein can be used to neutralize botulinum neurotoxin and are therefore also useful in the treatment of botulism.

This invention relates to stable formulations of multiple antibodies comprising a plurality of anti-botulism antibodies and an effective amount of a succinate buffer, an effective amount of arginine, wherein the antibodies are present in substantially equal concentrations and the pH of the formulation is between about 5 and about 6.5.

The present invention is based on the identification of synaptic vessel glycoprotein SV2 as the BoNT / A receptor and the further identification of various BoNT / A-binding fragments of SV2. The disclosure here provides new tools for diagnosing and treating botulism.

The present invention relates to the isolation of polypeptides derived from the Clostridium botulinum neurotoxin and the use thereof as immunogens for the production of vaccines and antitoxins, as well as research and drug development applications. Clostridium botulinum is responsible for food bone botulism, a severe and often deadly disease. Botulinum neurotoxin binds to neural cells and are translocated into the cytosol. The toxin then prevents neurotransmitter release by cleaving a SNARE protein. A double mutant E224A / E262 full length botulinum neurotoxin Type A holo form was successfully cloned and purified, which lacks the endopeptidase activity involved in the toxic action of the BoNT, and thus leading to its detoxification (DR BoNT / A). This new molecule can be used as an antidote against botulism, and also as a vaccine candidate for botulism. Due to the poor availability and extreme toxicity of native holo-toxin, a nontoxic form of the holo-toxin is highly desired for research and vaccine development. The full length DR BoNT / A protein has been expressed in E. coli as a soluble form.

This invention is directed to preparation and expression of synthetic genes encoding polypeptides containing protective epitopes of botulinum neurotoxin (BoNT). The invention is also directed to production of immunogenic peptides encoded by the synthetic genes, as well as recovery and purification of the immunogenic peptides from recombinant organisms. The invention is also directed to methods of vaccination against botulism using the expressed peptides.

The present invention relates to methods and systems for administering antibody therapeutic agents. The methods include administering one or more (e.g., two or three) binding agents, wherein each of the binding agents has one or more monomers that have a binding region that is specific to a portion of a disease agent and one or more copies of a tag. The binding agents can be specific to one or more portions of the same or different disease agents. The tag is the same for each of the binding agents. The methods include administering an anti-tag antibody, wherein the anti-tag antibody has an anti-tag region that is specific to the tag, and can have an immunoglobulin (e.g., IgA, IgD, IgE, IgG, and IgM). Disease agents include bacteria, bacterial proteins, viruses, viral proteins, cancer cells, and proteins or toxins produced therefrom or from other sources such as snakes, insects, plants, etc. In particular, the present invention includes methods and systems for binding agents having one or more monomers that are specific to neurotoxins that cause botulism.
